The yokogawa dcs or any other dcs consists of a minimum of one field control station and a human interface system.

In an FCS( Field control station) there are different nodes consisting of different cards to which the inputs are connected and outputs are taken out after processing. The selection of cards and the number of cards in each node depends on various parameters.

The selection of these cards and the loading of them in each node taken into account of all the parameters is called NEST LOADING. It depends on whether the input or output is digital or analog.. voltage or current... coming from a RTD or thermocouple or whether its a field-bus input etc.. and the CPU loading.
